Develop a SEARCH (or script to be shipped in the /foswiki/tools directory) which will report existing topics which already have content that may be interpreted as paragraph indent

Foswiki release upgrades: Should the presence of this tool simply be advertised in the release notes, or should we add a configure checker that adds a warning/error until you run the tool? NB: Upgrade packages are simply a tar -xzf of the upgrade tarball, nobody runs an actual upgrade script as such...

Those upgrading WysiwygPlugin on older Foswikis: Disabling the indent feature should be enough?

Just thought I'd mention that I'm looking forward to this feature. I'm migrating some existing content from Mediawiki to Foswiki right now, and this is one of the features that's missing in Foswiki TML, so it will be nice to see this implemented.

Issue is related to blockquotes entered as a single line, or as multiple lines but using hidden whitespace. TMCE gets confused and newline creates a new block.

Later... So "Enter" key consistently in TMCE always continues with a new instance of whatever block element you are in. <li> ... enter creates a new list item. This is consistent for lists, paragraphs, and blockquotes too. If you use the TMCE ["] button to create a blockquote, it also creates a paragraph, so you are actually typing inside a <blockquote><p> block. And enter splits the paragraph. When TML generates the blockquote, it does not create a paragraph block unless there is a blank line after the blockquoted. No blank line creates a hidden whitespace span, but that doesn't create a block element, and the newline still splits the blockquote. (I suspect that this deserves it's own task.)

blockquotes make the "de-indent" button active

confirmed

clicking de-indent in a blockquote makes it actually indent

Not on chrome or firefox on Linux. However using Release1.1, any indenting is lost on save.

the second blockquote on the page has a gray background, but it is not clear how it got there or how to remove it

This is related to tmwiki generating stylized blockquotes, where foswiki uses css

a link makes the unlink button highlight

Correct. On new Wysiwgy / TMCE, all links are "real" HTML links, and the unlink button is active so that the link can be removed.

no feedback is given on a special block like verbatim - the FORMAT dropdown does not show the selected style
